say maybe 5-7 cars, whadda ya got?
I would suggest the Midland GXT710VP3. This model is the most powerful consumer radio that we sell, and should get around a mile or so of range. It has the same range as the GXT850VP4 (reviewed here), but is missing the group mode and waterproof features which are not typically important for your use.
Hope this helps.
sounds good, we recently took a 2 1/2 hr. trip with 5 cars, i was the lead car and could not talk to the 3rd car in the line-up and would have to relay messages down the line. i hope with these radios we can remedy that.
